SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 236,907, dated January 25, 1881. Application filed September 24, 1880. (Model.)

To all whom it may concern 1 Be it known that I, CHARLES MowREY, a citizen of the United States, residing at Stockton, in the county of San Joaquin and State of California, have invented certain new and useful Improvements in Sulky-Plows; and I do hereby declare the following to be a full, clear, and exact description of, the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the. accompanying drawings, and to letters or gures of reference marked thereon, which form a part of this specification, in which- Figure 1 is a side elevation with one wheel removed, Fig. 2a plan view with the seat removed; Fig. 3, a front elevation with the footrest and a portion of its supporting-rod broken away; Fig. 4, a rear elevation with a portion of the plow-beam broken away; and Fig. 5, detailed views of the wheel-hub and axle and hub-box.

My invention relates to plows; and it consistsin means, hereinafter to be fully described and sought to be particularly specied by the claims, first, for adjusting the plow-beam to or from the landside, so that a large or small furrow may be turned;l secondly, for adjusting and rendering the draft -tongue interchangeable from a'ri gid toa yielding tongue.

In the accompanying drawings, the letter A indicates a frame having a front cross-rod, B, and a rear cross-bar, C. A shaft, D, extends across the rear under part of frame A, and is supported by boxes E, which are formed as a Sleeves F it on this shaft outside of the frame, and from the sleeves there extend arms G, which connect with the sleeves I-I on the axle I, which stands in front* of the shaft I). Toward the front of the frame A, and extending across the same, is another shaft, J, which is journaled in boxes formed on the under side of the frame. To this shaft on both sides of the frame, outside thereof, there are keyed the arms K, to which are connected the links L, which unite with a sleeve, M, on the axle I just outside ot the frame. A lever, N, is keyed to one end of the shaft J, and is provided with a catch, preferably a spring-bolt, which engages with the serrated face of the segment O, which is attached at its center to the shaft J and one end to the rod B. When the lever is moved backward it raises the plowsbut of the ground.

The spindle of the land-wheel is connected to the axle I by means of the crank l?, one end of which forms a sleeve, so as to fit over the end ofthe axle. To the inner side of this sleeve there is connected a lever, Q, which is provided with a spring-actuated bolt, that engages with a segmental rack, R, connected at its center to the axle I and at one end to the shaft D, while the other end is opposite to the journal of the land-wheel.

The seat S is supported by standards T, which pass through the frame A, and are connected by means of sleeves formedv on their lower ends to the axle I, while a rod, U, or its equivalent, extends from the seat to the foot-rest V, to which it is connected, and which is secured to the cross-rod B, as illustrated in Fig. 2.

The construction and operation of the foregoing parts, so far as described and set out in my patent of November 13, 1877, No. 197,160, constitute no part of my present invention, and therefore will not be any lnore enlarged upon in this specification; but I will now proceed to devote my description tothe parts constituting my present invention.

The rst part relates to the adjustment of the plow-beam. The letter A' indicates the beam, and B the plow. The beam passes from rear to front of the wheeled device, and is sustained by the swivel-supports C and D. The support C is composed of the two plates a and b, the lower plate being held to the shaft J by means of a sleeve, E', so that it may slide along the shaft from one side of the frame toward the other, while the top plate is swiveled by a pin and nut to the lower plate, and is provided with the brace c, through which the beam passes. rlhe support D is composed of the plates d and e, the plate d being secured to the shaft D by sleeves, as illustrated in Figs. 2 and 4, in a way that will prevent it from sliding from side to side. The plate e is swiveled to the lower plate by a pin and nut, and is also provided with a brace, f, composed of two upright bolts, a connecting cross-plate, and nuts, and through the brace the beam passes. A lug, g, projects from the lower part of sleeve E', and through the lug there works IOC a crank-screw, G', which is journaled in suita ble boxes under frame A in such a manner that when turned it will move the support C' along the shaft J. As the support C' is moved from side to side of the shaftJ it carries with it the forward part of the beam, which causes the beam throughout its length to change its Obliquity, the swivel-braces permitting the necessary swinging around of the beam, thereby adjusting the landside of the plow to or from the landside, whereby a large or small furrow is cut according to the degree ot adjustment.

Another feature of my invention relates to the draft-tongue, which is indicated by the letter H'. This tongue is hung or hinged at the point h to the braces I' and J', one of which is fastened to the end of rod B and the other to the bar C. The rear end of the tongue ts into the socket K' formed on the end of bar C. This socket is larger than the diameter of the tongue, so that the latter may have a vertical play therein. A chain, rod, or link, L', is connected to the tongue near its rear end, and extends down to and is connected, by a pin or otherwise, with an arm, M', which is secured to the lower end of lever N, so that when the lever is pushed back it will press the tongue trmly on the bottom of the socket K', holding it there, and at the same time causing the heel of the plow to rise out of the ground.

By constructing theparts so that the tongue will have the operation described the device is better suited for plowing on uneven or knolling ground, since the plows can enter the ground to a uniform depth. lt also admits of the plows being easily lifted out of the ground, the points being lifted out iirst. and then when the plows are lifted out they can be raised higher than they otherwise could. 'hen this construction is used on gang-plows the arm M' is fixed near the middle of the gang-shaft, so that it may work the gang more satisfactorily than when located at the end of the shaft.

Each wheelhub is provided with the keyseat i', and around the axle I there is tted a shouldered thimble, N', which is provided with a ange, j, that lits over the sleeve H, and with a key or feather, k, which ts into the seat t" and causes the thiuxble to turn with the wheel. A hand, 0', is fitted over the outer end of the sleeve N' and bears against the outer edge of the hub, so that the hub is between it and the shoulder of the thimble, as illustrated in Fig. 5. A uut, P', is screwed onto the end of the shaft I against the band 0. By constructing the parts as thus described all mud or dirt is excluded from between the hub and its axle, whereby the parts will run easier and longer, and when necessary they can be more easily repaired.

Having described my invention, what I claim is- 1. The combination of the plow-beam A', the swivel-support D', secured to the shaft D, the sliding support C', secured to the forward shaft J, and means for moving the same laterally, substantially as set forth.

2. The combination of the plow-beam A', the swivel-support D', the sliding swivel-support C', secured to the shaft J by plates a b, and sleeve E', and crank-screw G', substantially as described.

3. The hinged tongue H', in combination with lever N, arm M', rod L', braces I' and J', and a rest for the rear end ofthe tongue, substautially as described.

4. The combination of movable frame A and plow-beam A', lever N, shafts J and I, and connecting-cranks, hinged tongue H', arm M', and rod L', substantially as described.

In testimony whereof I ax my signature in presence ot' two witnesses.

CHARLES MOWREY.
